hey guys, rookie mechanic here, got a bad leak in the front right of my trannie (th350). If my truck sits for a day the leak isn't to bad, but when 2-3 days pass there is a huge puddle. Have been doing a little research and I am going to replace the filler seal, and lines. My question is, is there somethings i should be looking out for? and are there any other seals that i might be over looking that should be replaced? I plan on keeping the truck for a while. The pan gasket is new and sealed properly. and I am going to have a couple extra o-rings on hand incase i booger one up, as well as checking to ensure there is no burr to cut the new seal up. Thanx any advise is appreciated!!
